32/8 channel bonding

As we know that Arris has released Surfboard SB6190 the fastest DOCSIS 3.0 cable modem with 32x channel bonding downstream speed up to 1.4Gbps. Surfboard SBG7580AC is the wifi router with built-in the fastest cable modem today.

There is always a question why purchasing a high speed of up to 1400Mbps cable modem when there is no existing broadband cable providers deliver internet service plan with high speed up to 1Gbps. Typically most cable providers with the ultimate plan can be delivered to the subscriber’s premises in its best when the modem used by the customer is DOCSIS 3.0 cable modem with 16/4 channel bonding or higher such as TP-link TC7620 and Linksys CM3024. Technology evolves very fast, probably in a short time most ISPs will upgrade their infrastructure and ready for delivering higher internet speed to the customers and your cable modem is ready for that. Surfboard SBG7580AC is ready for the future of the highest speed internet package deliver by the ISPs.

Cable modem with wifi

Traditionally building wifi network in home you require separate modem and wireless router. Surfboard SBG7580 is an all-in-one product that integrates the high speed DOCSIS 3.0 cable modem and wireless router in a single compact device. This product comes with wireless AC1750 technology, ideal for home users that demand simplicity in building wifi network. Arris should’ve upgraded the wifi technology to the upper level something like wireless dual band AC2400 or higher to lift the whole performance of this product including longer range.

When the wifi signal doesn’t penetrate up to the farthest corner of the house you just add one of best wireless range extender such as wall-plug model Netgear EX7300 or desktop model Linksys RE6500HG range extender. All models of range extender are mostly universal that can work with any wireless gateway including this Arris Surfboard SBG7580.

Comparison

Currently there are few models of wireless cable modem router combo available in the market including most popular Surfboard SBG6900, Netgear Nighthawk C7000 and soon Linksys release new modem gateway Linksys CG7500 wireless AC1900 cable modem router.

To see how they all the three modem router combo compared, take a look at the following two comparison tables. Table 1 shows you spec comparison between Arris Surfboard SBG7580AC and Netgear Nighthawk C7000, and table 2 shows you spec comparison between SBG7580 and Linksys CG7500.

Modem

See that Surfboard offers the fastest speed DOCSIS 3.0 cable modem, the most number of downstream channel bonding delivering technically internet speed up to 1400Mbps. Currently Arris has Surfboard SB6190 as the fastest cable modem with 32x channel bonding downstream.

Wifi

With the built-in fastest modem, unfortunately the wifi module is not lifted to the upper level such as based on wireless AC1900 at least like those competing products C7000 and CG7500. However, if you compare the prices Surfboard SBG7580 is still more economical than Linksys.

All other features look like the same including the number of Ethernet ports. However, Linksys offers only one gigabit Ethernet LAN port and too sad no USB port is available for storage or printer sharing.

Are you better off with the faster wifi speed of the 6900 or the cable speed of the 7580?

Only about a $50 difference between the two. Seems to me that higher wifi speeds are more likely to be obtainable than higher cable speeds but I can’t find any performance comparisons between these devices. I thought that was where this article was going but then the 6900 wasn’t included in the comparison chart.
